The principle of solar lawn light

Solar energy has become the hero of energy saving and environmental protection nowadays. Electric water heaters and gas water heaters are gradually replaced by solar water heaters, and traditional street lights are gradually replaced by solar lawn lights. System composition of solar lawn light The solar lawn light is an independent solar energy system. It can independently convert solar energy into electrical energy, and can convert electrical energy into thermal energy for lighting and decoration without the need for wire transmission. The main components of the system are photovoltaic power generation system and power supply system. Photovoltaic system A stand-alone photovoltaic system usually consists of three parts: solar cell components; power electronics such as charge and discharge controllers, inverters, test instruments and computer monitors, and batteries or other energy storage and auxiliary power generation equipment. Photovoltaic power generation system has the following characteristics: no rotating parts, no noise; no air pollution, no waste water discharge; no combustion process, no fuel; simple maintenance, low maintenance cost; operational reliability and stability; as a key component of solar cell life Long, crystalline silicon solar cells can last for more than 25 years and can easily be scaled up to generate electricity as needed. Power supply system The solar lawn light is a small solar power supply system. Its structure is very simple. It is mainly composed of solar panels, charge and discharge controllers, batteries, lighting circuits and light poles. Maintenance of rechargeable batteries, automatic control circuits, lamps and other components. Light source advantages of solar lawn lights At present, most solar lawn lights use LEDs as light sources. The LED has a long service life, can reach more than 100.000 hours, and has a low operating voltage, which is very suitable for solar lawn lights. In particular, LED technology has made a major breakthrough. In the past five years, its characteristics have been greatly improved, and its cost performance is relatively high. In addition, LEDs are powered by low-voltage direct current and their light source control costs are low, allowing brightness and frequency to be adjusted without adversely affecting the performance of the LEDs. Due to the unique advantages of solar lawn lights, the design methods of solar lawn lights and power systems have developed rapidly in recent years. Lawn lights have low power and are mainly used for decoration. It is suitable for places with high mobility requirements, difficult circuit laying and high waterproof requirements.
